wow - that's interesting...I don't think I'll try it any time soon, but damn I can't even imagine the rush - I've been taking ambien for about a year now, (less frequently now, due to my opiate addiction-I don't seem to need it) but when I do take it orally - usually 15-30mgs it hits hard and fast - like a freight train..... It would probably blast you off pretty good.
By the way, how good does it disolve? Also what filtering precautions would you take? Just curious
